The draw Start and End slider bars in the Control Strip provide a very powerful way of viewing an embroidery and understanding exactly how it is formed. They allow you to progress forwards and/or backwards through an embroidery stitch by stitch and isolate a specific sequence of stitches. If desired, select the visible stitches as a block to work on (Select All Visible 
) or use a feature such as global morphing without affecting the hidden stitches. You can use Ghost Mode 
to show the overall shape of the embroidery while only working on visible stitches. Changing the range of stitches can be combined with selecting colors to display a particular set of stitches that would be difficult to isolate with other functions.
